Check your VGA cables to make sure it's properly connected (if you haven't already). If that does not work, Take the CMOS battery out of your motherboard and leave it out for a minute, then put it back in. If that still doesn't work, make another post with more specific information about your system.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Without seeing the specs of the adapter it's hard to tell the voltage is correct but what you need to be concerned about is the amperage(mA) USB ports on computers only put out a max of 500mA per port the tablet charger could put out more than that.
After i Read your Explaination,i really sure if the Problem is at your Computer POWER SUPPLY. Change your Power Supply to Higher Watt. i Recomended to you to Using SIMBADA Power Supply ATX. and to Fix your HDD bad Sector,Try to use LLF (Low Level Format). LLF will destroy all data and Partition.So after you Format using LLF,you need to make a New partition at your HDD. LLF is Working for me to Fix Bad Sector in a So many times.
IT seems that the power destroy your power supply, the question now when you try to turn your computer, do you hear anything? or it doesnot turn on at all. if this is the case, replace the power supply.
As for known problems, this sounds like a failure in one of the circuit boards, either the one on the hard drive or the USB conversion board. If it is off warranty, the simplest method to test this is to transfer the drive into a new enclosure which you should be able to do at any PC shop.
If the drive works in the new drive enclosure then you're good to go. If it doesn't then you will likely need to replace it and if there is important data on the drive enlist a pro to recover the data.
Try the swap and let me know how you make out, if the results are indicating the need for a pro then reply with your Country, State and City and I will point you to an appropriate pro near you.
As far as the yellow light on the power supply is concerned. Unhook it from the Xbox 360 and only plug it into a power outlet. If the light is yellow then the power supply is bad. If the light stays green then plug it into the xbox 360, if it tells yellow then, at that point you know that the main board is causing the yellow light on the power supply and that means the main board is bad.
the power supply is probably bad. It's really hard to tell without a little more information. When my power supply went bad on my computer. the hdd light would come on but nothing else and the computer would not even try to start.the power supply puts out several different voltages with both positive and negative outputs.
